In order to prevent a vehicle from running with an inappropriate vehicle height, a vehicle height restoring speed controller determines whether the vehicle is starting or not. When the vehicle is starting, the vehicle height restoring speed controller switches a restoring speed of the vehicle height to a restoring speed for a vehicle's stopped state and not for a vehicle's running state, and provides control so that the vehicle height is swiftly adjusted to a reference vehicle height. This prevents the sustained inappropriate vehicle height, and thereby prevents the resulting hindrance to vehicle running.
